| <i>Bacillus oceanisediminis</i>
| |
|
| |
| ==Description and significance==
| |
|
| |
| <i>Bacillus oceanisediminis</i> is a rod-shaped aerobic bacterium that is gram-positive and spore-forming (1, 2). <i>B. oceanisediminis</i> was isolated from a sample of sediment from the South Sea in China at a depth of 823 m (2). It is a decomposer which means that it helps clean sediments in the ocean ecosystem and lives in marine sediment. <i>B. oceanisediminis</i> can be found singular and/or in pairs (2). Due to its ability to grow in a temperature range of 4°C-45°C and a pH of 6-10, it can survive in many different environments (1).

|
| |
| ==Genome structure==
| |
|
| |
| <i>B. oceanisediminis</i> has a large genome size that is approximately 5.8 Mb (1, 2). It was found that <i>B. oceanisediminis</i> has a larger genome size than most <i>Bacillus</i> species (1). This means that it has the possibility of being very diverse due to its ability to encode a variety of genes. It has a genomic DNA G+C value of 44.8 mol% (2).16S rRNA gene analysis showed that <i>B. oceanisediminis</i> is closely related to <i>Bacillus firmus</i> and <i>Bacillus infantis</i> (2).

|
| |
| ==Cell and colony structure==
| |
|
| |
| <i>B. oceanisediminis</i> is a gram-positive bacillus (rod-shaped). It is approximately 2-3µm long (1). It has four major polar lipids that are made up of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, and an aminophospolipid that is unknown (2). Its isoprenoid quinone is MK-7 and there is one major fatty acid which is iso-C (15:0) (2).
| |
|
| |
| ==Metabolism==
| |
|
| |
| <i>B. oceanisediminis</i> contains phosphotransferase systems. Phosphotransferase systems are used to obtain different carbon sources. Some carbon sources utilized by <i>B. oceanisediminis</i> include glucose, mannitol, sucrose, maltose, and fructose (1). Fermentation can also occur in <i>B. oceanisediminis</i>. Acetate, ethanol, and lactate are some of the fermentation products that were found in <i>B. oceanisediminis</i> that helps aid in fermentation. Proteins such as copper, cobalt-zinc-cadmium and tellurium resistance proteins were found in <i>B. oceanisediminis</i> to be connected to biomineralization (1). This means that they are able to create minerals.
| |
|
| |
| ==Ecology==
| |
|
| |
| <i>B. oceanisediminis</i> can grow at a temperature of 4°C-45°C and has a pH ranging from 6-10 (2). The best growing conditions for this bacterium is 37°C at a pH of 7.0 (1). It is halophilic and can live in various habitats due to its range of growing temperature and pH (1, 2). <i>B. oceanisediminis</i> is positive for oxidase and catalase, which means that it uses oxygen as its main respiration source (2).
| |
|
| |
| ==Pathology==
| |
|
| |
| <i>B. oceanisediminis</i> is resistant to aztreonam and was found to be susceptible to many antibiotics such as ampicillin, chloramphenicol, and penicillin G. It is not known whether <i>B. oceanisediminis</i> is pathogenic or non-pathogenic (2).
